The nuclear missile submarine Montana sinks with all hands near the Cayman Trench in the Caribbean Sea. Members of the underwater oil rig "Deep Core," led by Virgil "Bud" Brigman and his estranged wife, Lindsey Brigman, must work with a team of Navy SEALs to conduct a salvage operation on the sub. During the operation, the group encounters alien lifeforms which they dub non-terrestrial intelligence, or NTIs. The SEAL commander, Lieutenant Coffey, views them as a threat and attempts to use a nuclear warhead from the submarine to destroy them. Bud and Lindsey must work to save not just the aliens, but the entire world.
